Actionscript 3 使用变量一次只允许播放一个视频

我最近创建了一个有四个按钮的项目。每个按钮向舞台添加一个FLV播放器并播放视频。在测试过程中，我注意到在第一个函数加载完电影之前单击另一个按钮，将播放两部电影

有没有更有效的处理方法？我觉得这里有很多冗余代码，有没有更好的方法来执行以下操作：

• 按下按钮一
• 加载一个视频
• 忽略所有其他事件侦听器，直到电影结束，或用户解除视频（单击以解除）

我最初认为创建两个函数是个好主意，一个删除所有事件侦听器，另一个添加所有事件侦听器。按下按钮后，在加载FLVPlayback之前，删除所有事件侦听器。电影完成后，将所有听众添加回。这似乎很费力，而且效率很低

我写了下面的代码作为我尝试做的一个例子。（但每次都会输出相同的字符串“One Can play”）

我尝试了这段代码，我让它“正常工作”，但每个函数都会将canLaunchMovie设置为true

import flash.events.Event;

var canLaunchMovie:Boolean;

buttonMCOne.addEventListener(MouseEvent.MOUSE_DOWN, playMovieOne);
buttonMCTwo.addEventListener(MouseEvent.MOUSE_DOWN, playMovieTwo);
buttonMCThree.addEventListener(MouseEvent.MOUSE_DOWN, playMovieThree);
buttonMCFour.addEventListener(MouseEvent.MOUSE_DOWN, playMovieFour);

function playMovieOne(e:Event):void {
    if(canLaunchMovie = true){
        this.canLaunchMovie = false;
        trace("One Can Play"); // do all that video stuff for video one
    } else {
        trace("I can't do that(play movie one) Dave");
    }
}

function playMovieTwo(e:Event):void {
    if(canLaunchMovie = true){
        this.canLaunchMovie = false;
        trace("Two Can Play"); // do all that video stuff for video one
    } else {
        trace("I can't do that(play movie two) Dave");
    }
}

function playMovieThree(e:Event):void {
    if(canLaunchMovie = true){
        this.canLaunchMovie = false;
        trace("Three Can Play"); // do all that video stuff for video one
    } else {
        trace("I can't do that(play movie three) Dave");
    }
}

function playMovieFour(e:Event):void {
    if(canLaunchMovie = true){
        this.canLaunchMovie = false;
        trace("Four Can Play"); // do all that video stuff for video one
    } else {
        trace("I can't do that(play movie four) Dave");
    }
}

您不需要有多个flvplayback。

您只需更改flvplayback的

源代码。
Arg。。所以从技术上来说，这个更新不起作用。我做的作业总是正确的，而不是做平等性检查。它之所以有效，是因为每个按钮都会指定canLaunchMovie=true；与论坛网站不同，我们不使用“感谢”或“感谢任何帮助”或签名。顺便说一句，这是“提前感谢”，而不是“提前感谢”。
